For launching programs from Python, we recommend using pwntools, but subprocess should work as well. If you are not using one of these two, you will suffer heavily when you get to input redirection (for that, check out the stdin and stdout arguments to pwn.process or subprocess.Popen).
For reading and writing directly to file descriptors in bash, check out the read and echo builtins.
You will find the env command useful, and the exec bash builtin.
Quick refreshers on fork() versus exec*() here and here and here.
Remember to wait() on your children! If you use subprocess.Popen, pwn.process, or good old fork(), your parent will keep executing and, unless it waits for the child in some way, will just terminate! This is almost never what you want.
